5 long-standing problems Jurgen Klopp has solved at Liverpool this season

#4 The left-back conundrum

Robertson had a terrific season

Whenever fans are asked about their favourite left-back this century, they conveniently skip to this decade to land on John Arne Riise or even Fabio Aurelio. It says as much about the subsequent left-back signings as the recruitment team, that the club has seen no fewer than seven players in the past decade trying to solve the problem.

The arrival of Andy Robertson from Hull City for £8 million last summer was met with as much skepticism as one could expect. Initially, it went according to the script as the 24-year-old barely got a chance to play with Alberto Moreno finally finding consistency. However, an injury to the latter changed things.

Robertson was thrust into the first team and as games went on, he began to show why the left-back problem seems to have been solved for the near future. Defensively solid with a wicked delivery from out wide made him the perfect package as the Reds went hunting in Europe. In fact, the full-back has created a clear-cut chance every 243 minutes, which is better than the likes of Cesar Azpilicueta, Kyle Walker, Hector Bellerin and Kieran Trippier.

As Klopp emphasised, the Scot had to get up to speed in terms of the playing style in the initial months. The latter looks to have taken the gaffer's instructions well as indicated by his performances.

Thus, Klopp has definitely filled the huge void in the left-back slot, solving another major problem.
